Summary

OpenPanel js-runtime through 2.3.0 contains a sandbox escape vulnerability in the JavaScript webhook template validator that fails to block computed member access to constructor chains. Attackers with project write access can create webhook templates using computed property notation to access Function constructor and execute arbitrary code in the worker process.

Risk Assessment

The risk is the potential for arbitrary code execution in the worker process, which could lead to application takeover or data integrity compromise.

Recommendation

It is recommended to immediately upgrade OpenPanel js-runtime to a version newer than 2.3.0 that fixes the vulnerability, and to restrict project write access to trusted users only.
